I contacted sapphire who suggested it might be a bios issue so I updated the bios on my existing foxconn mobo which made no difference then I bought, installed and upgraded the bios on the asrock mobo which again didn't help. The rx 480 appears to power up fine and if I leave my speakers on I can eventually hear the windows login music play but I get no signal at all on a variety of monitors. Gpu drivers: not applicable, uninstalled previous drivers before rx 480 attempted installĭescription of Problem: tried to install my new rx 480 but I get no display signal out of any of the displayports or hmdi outputs (don't have the equipment to test the dvi-d outout). Operating System & Version: windows 7 home premium
Motherboard: have tried both foxconn h61mxl-k and asrock h61m-dgs
GPU: originally a sapphire HD7950 3Gb, upgrading to RX480 sapphire nitro oc+ 8gb
